The last of the Disneyland Haunted Mansion Diorama rooms is the Hallway. This one is a simple construction, mostly used to house a 50% scale build of the Demon Clock from The Disney Experience web site. http://www.disneyexperience.com/ This is a great site for any fan of Disneyland.
This first image shows the basic construction. This is one more of the 1 foot square rooms, sized like the others. On the left side is a straight wall with a bit of Haunted Mansion Foyer wallpaper. The right side is set at an angle for a little more interest with the spooky eyes wallpaper from the Disneyland Haunted Mansion Hallway. The wood flooring is just some wood contact paper. And of course the Demon Clock from The Disney Experience built at 50% scale to fit the model. After finishing this room I picked up a smaller paper model from Trader Sam at The Disney Experience that would have been a better fit, but I already built this one, so it stays.
Here is the finished model. This includes a little lead figure suit of armor, that I put on a box to bring it up a bit in the display. The door on the right is just a print out pasted onto a piece of black foam core, cut out, and attached to the wall. The picture and the Tomb Sweet Tomb on the wall are from a little Disneyland Haunted Mansion paper box that I found on one of the Disney web sites, family.go.com You can find tons of great Disney stuff on this site. The link will take you to the Disneyland Haunted Mansion paper box.
